To all whom it may concern: Be it known that I,-.TI-IOMAS J. Wnmnims,

, a citizen of the United States, residing at great variety oi":v uses.

Washington, District of Columbia, have innew and useful improvements" in chainswhereby the latter may be usedboth as a. protector and a-g'uide for an inclosed chain orcable, so as to adaptthe: chainior'a In carrying out the objects of the inventv tion generally stated above, it will of course, be understood that the same is susceptible of a wide range of details and structural'iar rangements, a preferred and, practicalfem+ bodir'nent of which'is shown in the accompanying drawings, wherein+ Figure 1 is adetail View of the invention showing the same used in connection with an automatically operating releasing device tor fire engine houses. Fig. 2is a snnilar"v-iew}- showing the invention used-,fonsuspending lamps and also serving as a guide and protector for the feed'wirelof the same; Fig. 3 is a side elevationof a portion of the improved chain, showing the'universal connection be; tween each link thereof. Fig.4 is a central longitudinal sectional view takenthrough one of the links and'a Dortlbnof theadjoining links. 7 'It is to be understood at the'outset, that the two uses .of the improved chain illus trated in the, drawings, is but a'iew ofthe:

many uses to whichtlie' invention may be'put.

Referring to said drawings, the improved chain may-be composed ofa plurality of-o-pen links 1, the ends of which are transversely rounded and widened to provide, respectively, a socket member and a ball member, as indicated at-2 ind 3, the rounded siirface or socket portion 3 projectin g'beyond the end of the link and the rounded-surface terior' of thelink, as is'shownmor I in Figs. .3. and 4 oi the accompanying dizayw ings. -The ball and? the socket pcrtiens of alined openingsthrough the links g, ronfidedi surface, the rounded provided with 'alined openings, for ball portion 2 projecting toward the ins, j

' thelinks are preferably integral therewith, and each is providedwith an opening 4,

which aline, so as ermit a chain, cable-or i =the like to be passe entirely through "the chain, as is shown in'the tvv examples of f uses to which-the invention may be applied inFigs. l and'Q-Q' f 7 71 "The hall and socket portions ofthel ends of the linksflare rfonndedthe "ball ends being or" a smaller size than the concaved ends, so

that when'the are togethentheball end ofeach link wi'lllfit within the socket end or the adjacent link, as'shown in'fF-igsfi? and 4, to; form a ball and. socket joint, between each link, which permits of the said links having arela-tiv'e movement to the necessary flexibility tothe chain.

the bait members and the socketmembers of the links'are comparatively wide-they project well beyond each side of the link, and thereby,provide an enlarged: bearing surface which permits the links to havethe desired relative movements.- y I I As has been before stated the chain-{may be put to a large numberof uses both as a guide and a protector, as it'will be readily seen that through the described universal cormection between each link and the alined.

openings through the same, the chain, cable, or wire that is inclosed by said links will be thoroughly protected, and Where amovement ofthe inclosed chain, or the like, relativeto theprotector and guide is desired, the

sametofbemadilyhad;

I *1. A'ichaiii link having its ends trans: versely widened and. provided, respectively,

lt-will be seen from the foregoirigflhat as permit the with an-.. inwardly projecting. rounded stirsurfaced face and an outwardlyprojecting rounded:

surfaces and forming a socket member, the other end members form a guiding channel extending projecting inwardly of its link and fonning through the chain. 10 r a ball member, said socket member and said In testimony whereof I hereunto 'affix my ball member having openings through them signature in presence of two witnesses.

which are in alinel'nent, whereby, when said THOMAS J. WILLIAMS.

links are assembled, the ball member of one W'itnesses:

link engages with the socket member of the C. A. BAKER,

other link and the openings through said, G. A. OOTTER.-
